Villarreal are hoping to have Gerard Moreno available for selection after the striker left the Spain camp early through injury. Samuel Chukwueze misses out owing to a hamstring problem. Unai Emery could name the same XI that started the 2-2 draw at Atletico Madrid prior to the international break. Hans Hateboer and Luis Muriel sit out the trip to Spain through injury. Josip Ilicic and Ruslan Malinovskiy were both subs against Fiorentina at the weekend and should return to the XI. Marten de Roon has served three of his four-match ban in Serie A, so is available here, but a lack of game time is likely to count against him.
